Description

Technical Field

[0001] This utility model relates to the field of hydrogen peroxide proton exchange membrane technology, specifically to a hydrogen peroxide proton exchange membrane cutting device with positioning function. Background Technology

[0002] A proton exchange membrane (PEM) is a special semi-permeable membrane specifically designed to conduct protons while simultaneously acting as an electronic insulator and a barrier against reactants. In a proton exchange membrane fuel cell (PEMFC) or proton exchange membrane electrolyzer, the core function of the PEM is to isolate reactants and transfer protons, while preventing electrons from being directly conducted through the membrane. The PEM is not only the electrolyte carrier but also the critical site for the electrochemical reaction between hydrogen and oxygen; its performance directly affects the efficiency and lifespan of the fuel cell. During its production, it requires cutting and trimming.

[0003] In the existing hydrogen peroxide proton exchange membrane processing, due to the lack of an effective positioning and guiding mechanism, the proton exchange membrane is prone to shifting to both sides during the cutting process. This significantly reduces the cutting accuracy, and the inaccurate cutting will further lead to many adverse consequences, such as the subsequent processed products not meeting the standard requirements in terms of size and specifications. Ultimately, this results in a significant decrease in the overall yield rate, increases production costs, and also affects production efficiency and product quality to some extent. Utility Model Content

[0004] The purpose of this invention is to provide a hydrogen peroxide proton exchange membrane cutting device with positioning function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A hydrogen peroxide proton exchange membrane cutting device with positioning function includes a base, a support bracket is fixedly installed on the top right end of the base, a worktable is fixedly installed on the top left side of the base, and an exchange membrane is disposed on the top of the worktable.

[0007] A positioning unit is provided on the top of the workbench, and a tension adjustment unit is provided between the workbench and the support bracket.

[0008] The positioning unit includes a limiting groove formed on the top of the workbench, and positioning plates are slidably installed on both sides of the limiting groove.

[0009] A further improvement of this utility model is that a hydraulic cylinder is fixedly installed on the bottom of the workbench, a piston rod is provided on the extended end of the hydraulic cylinder, a connecting shaft block is fixedly installed on the other end of the piston rod, and push-pull rods are rotatably connected to both sides of the connecting shaft block. The model of the hydraulic cylinder is: STORZZW / ZWAS 2511.

[0010] A further improvement of this utility model is that: a rotating shaft is rotatably connected to the other end of the push-pull rod, the rotating shaft is fixedly installed on the bottom end of the positioning plate, and sliders are fixedly installed on both sides of the rotating shaft. The sliders are slidably connected in the inner wall groove of the limiting groove, and the limiting groove can limit the movement of the positioning plate.

[0011] A further improvement of the present invention is that the tension adjustment unit includes a support plate fixedly installed between the workbench and the support bracket, an adjustment block is slidably sleeved on the outer surface of the inner vertical rod of the support plate, a rotating rod is fixedly installed on the inner side of the adjustment block, and a tensioning wheel is rotatably sleeved on the outer surface of the rotating rod.

[0012] A further improvement of this utility model is that: locking tooth plates are fixedly installed on the outer side of the support plate at both the left and right ends, and sliding rods are fixedly installed on the outer side of the adjusting block on both sides of the fixed block, and the sliding rods can limit the movement of the locking block.

[0013] A further improvement of this utility model is that a locking block is movably sleeved on the outer surface of the other end of the slide rod, and a return spring is movably sleeved on the outer surface of the slide rod between the locking block and the fixing block.

[0014] A further improvement of this utility model is that a servo motor is fixedly installed on the upper left side of the front of the workbench, a drive rod is fixedly installed on the output end of the servo motor, and a cutting blade is fixedly sleeved on the outer surface of both ends of the drive rod. The model of the servo motor is: SIMOTICS S-1FT7.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] This invention provides a hydrogen peroxide proton exchange membrane cutting device with positioning function. By activating a hydraulic cylinder to cause the piston rod to extend and retract, the tilt angle of the two sets of push-pull rods can be changed, thereby driving the two sets of positioning plates to move relative to each other or in opposite directions, adhering to the two sets of exchange membranes and positioning them to prevent positional deviation during cutting, thereby improving cutting accuracy and promoting production efficiency and product quality.

[0017] This invention provides a hydrogen peroxide proton exchange membrane cutting device with positioning function. By pushing two sets of locking blocks inward, they disengage from the grooves of the locking tooth plate, releasing the lock. At this time, the locking blocks slide on the outer surface of the slide rod and squeeze the return spring. The position of the adjusting block on the vertical rod is moved up and down, thereby driving the tension wheel to move up and down. This allows adjustment of the tension of the exchange membrane. After adjustment, the locking blocks are released, and they rebound and reset under the elastic counter-push force of the return spring, locking the position of the tension wheel again in the groove of the corresponding locking tooth plate, further improving the cutting quality of the exchange membrane.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] like Figure 1-5As shown, this utility model provides a hydrogen peroxide proton exchange membrane cutting device with positioning function, including a base 1, a support bracket 2 fixedly installed on the top right end of the base 1, a worktable 3 fixedly installed on the top left side of the base 1, an exchange membrane 4 disposed on the top of the worktable 3, a positioning unit disposed on the top of the worktable 3, and a tension adjustment unit disposed between the worktable 3 and the support bracket 2. The positioning unit includes a limiting groove 31 opened on the top of the worktable 3, and slidably mounted on both sides of the limiting groove 31. A hydraulic cylinder 34 is fixedly installed on the bottom of the positioning plate 33 and the worktable 3. A piston rod 35 is provided on the extended end of the hydraulic cylinder 34. A connecting shaft block 36 is fixedly installed on the other end of the piston rod 35. Push-pull rods 37 are rotatably connected to both sides of the connecting shaft block 36. A rotating shaft 38 is rotatably connected to the other end of the push-pull rod 37. The rotating shaft 38 is fixedly installed on the bottom of the positioning plate 33. Slider blocks 39 are fixedly installed on both sides of the rotating shaft 38. The sliders 39 are slidably connected in the inner wall groove of the limiting groove 31.

[0026] Furthermore, by activating the hydraulic cylinder 34, the piston rod 35 is extended and retracted, which changes the tilt angle of the two sets of push-pull rods 37, thereby driving the two sets of positioning plates 33 to move relative to each other or in opposite directions, fitting onto the two sets of exchange membranes, positioning them and preventing positional deviation during cutting. Example

[0027] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the tension adjustment unit includes a support plate 11 fixedly installed between the workbench 3 and the support bracket 2. An adjustment block 12 is slidably sleeved on the outer surface of the inner vertical rod of the support plate 11. A rotating rod 13 is fixedly installed on the inner side of the adjustment block 12. A tensioning wheel 14 is rotatably sleeved on the outer surface of the rotating rod 13. Locking tooth plates 15 are fixedly installed at both ends of the outer side of the support plate 11. Slide rods 16 are fixedly installed on both sides of the outer side of the adjustment block 12 on both sides of the fixed block. A locking block 17 is movably sleeved on the outer surface of the other end of the slide rod 16. A return spring 18 is movably sleeved between the locking block 17 and the fixed block on the outer surface of the slide rod 16.

[0028] Furthermore, by pushing the two sets of locking blocks 17 inward, they disengage from the grooves of the locking tooth plate 15, thus releasing the lock. At this time, the locking blocks 17 slide on the outer surface of the slide rod 16 and compress the return spring 18. The position of the adjusting block 12 on the vertical rod is moved up and down, thereby driving the tension wheel 14 to move up and down as well. This allows the tension of the exchange membrane to be adjusted. After adjustment, the locking blocks 17 are released, and they rebound and reset under the elastic counter-push force of the return spring 18, locking the position of the tension wheel 14 again in the groove of the corresponding locking tooth plate 15. Example

[0029] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, a servo motor 32 is fixedly installed on the front left side of the workbench 3, a drive rod 321 is fixedly installed on the output end of the servo motor 32, and a cutting blade 322 is fixedly sleeved on the outer surfaces of both ends of the drive rod 321.

[0030] Furthermore, the output of the servo motor 32 drives the drive rod 321 to rotate at a constant speed, and the drive rod 321 drives the cutting blade to rotate, thereby cutting the exchange membrane.

[0031] The solution uses a PLC as the core control component. The PLC establishes a connection with the servo motor 32 and the hydraulic cylinder 34 through RS-485 communication. When it is necessary to start the servo motor 32 and the hydraulic cylinder 34, the PLC sends a start command to the servo motor 32 and the hydraulic cylinder 34 to start them.

[0032] The working principle of this hydrogen peroxide proton exchange membrane cutting device with positioning function will be explained in detail below.

[0033] like Figure 1-5 As shown, during use, firstly, by pushing the two sets of locking blocks 17 inward, they disengage from the toothed grooves of the locking toothed plate 15, thus releasing the lock. At this time, the locking blocks 17 slide on the outer surface of the slide rod 16 and compress the return spring 18. The position of the adjusting block 12 on the vertical rod is moved up and down, thereby driving the tension wheel 14 to move up and down as well. This allows adjustment of the tension of the exchange membrane. After adjustment, the locking blocks 17 are released, and they rebound and reset under the elastic counter-push force of the return spring 18, locking the position of the tension wheel 14 again. With the activation of the hydraulic cylinder 34, the piston rod 35 is extended and retracted, which can change the tilt angle of the two sets of push-pull rods 37, thereby driving the two sets of positioning plates 33 to achieve relative or opposite movement, fitting against the two sets of exchange membranes, positioning them and preventing positional deviation during cutting.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
